Any good resources for this event? A lot of my questions have been pulled from college-level texts (AP-level questions are what I'd consider the "easiest" level in my tests) and even some graduate, and I was wondering what resources were considered to be "normal" difficulty for this event.

Creol, the College of Optics and Photonics at the University of Central Florida is sponsoring this year's event and will be posting resources to its website.

I've been wrestling with this one for weeks. Because it's all algebra-based, we shouldn't need anything beyond AP 2 level problem sets for this event. Still, I ordered a book one step up and am testing that this season...the thing to remember is that the tests aren't supposed to be inaccessible, so it does seem like any textbook plus workbooks/end of chapter problems are adequate.

I personally used HyperPhysics and found it more than adequate

What level of math should I really be expecting for Division B.

I have already taken Algebra I and am taking geometry this year. Do I need anything beyond that?

How??
But if it works that would be fun.

So after the LSS is built, at designated times decided on this forum we all agree on a distance from center to what side for the target, and a position for the barrier (how far from front end and how far of center aligned it is) and then we time everyone. We all go through the event as mentioned in the rules and measure our scores. We trust people to be honest, because why lie.

If we want, we could keep track of the winners and recognize them in the end.

This could probably even be arranged without having everyone doing it at the same time. You could just post a certain setup and people could reply with their score whenever they have time.

Exactly.

Though it would be better if we still hold multiple competitions with deadlines for each.

Maybe we could have everyone do at least 1 test a week and share results.

I think we should just have someone pick a target, and whenever people have time they do it, and whoever got the most points pick the next target.

Minimal algebra. Tests should slant concepts, but be able to calculate speed of light in a given medium, use Snell's Law (that's new to B division this season, seems, even though it was typically assessed, anyway), calculate image properties, etc. Nothing too major...certainly none of the trig involved in some of the, ahem, challenge problems posted in last season's topic!

Here's the test I used for the UT Regional last season (given to both B and C division). It's probably much harder than most would expect in terms of content and math involved. I think surprisingly Beckendorff ended up beating every team (B and C) in terms of test points (aka excluding the LSS).

I really like that this year, the LSS has a magnetic base. Minor movements of the mirrors after letting go of them or adjusting my template were my biggest source of error last year, hopefully magnets will prevent that.
